Galatians 3:24-25 NKJV
24 Therefore the law was our tutor to bring us to Christ, that we might be justified by faith.
25 But after faith has come, we are no longer under a tutor.
The law was our tutor, or schoolmaster as it is translated in the KJV, and now we are no longer under that tutor.
However, that text does not limit the purpose of the law to only that of a tutor to lead us to Christ for the believer.
"Oh, how I love Your law! It is my meditation all the day." (Psalm 119:97)
For the child of God, the law, when properly interpreted within the context of the new covenant, is our love and our delight.
No longer bound by it, yes. But required to follow it all the same. A disciple of Christ will want to follow Gods perfect law anyway. It is what the Holy Spirit does in our hearts when we are born again.
